All I know is I have 24000miles on my 96 GSXR 750,and I have raced every CCS race in FL this year,and the motor still runs as good as it did when I bought the bike new.I can race 2 full weekends,and the bike is still full of oil,while other racers are adding oil to there bikes.I took my clutches out,because I thought with that many miles that the clutches wouldn't take race abuse,but to my amazament the clutches where fine,and when I measured the OLD clutches to the NEW Suzuki cluthches the OLD ones where alittle thicker than the new ones(by a few thous),so that shows there was NO wear in the clutches at all,and the plates looked brand new.To me Torco keeps the motor,and all the parts in perfect condition,even under extreme loads.
